19

Step-by-step explanation:

The vertical axis of a histogram indicates the total amount of people that meet the weights indicated in the x-axis in the analysed population. From data we can construct the following table:

x-axis y-axis

115 1

135 4

155 3

175 1

195 5

215 2

235 3

So there are: 1+4+3+1+5+2+3 = 19 team members included in the histogram.
